HENRY M. CASE, OF CINCINNATI, OHIO, ASSIGNOR T0 DILLA. C. LINNEMANN, OF

COVINGTON, KENTUCKY.

WINDOW-VENTILA'I'OR.

Application filed April 6, 1918.

To all whom it may concern:

Be it known that I, HENRY M. CASE, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invent ed certain new and useful Improvements in lVindow-Ventilators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification.

The object of my invention is to provide a simple, cheap and effective ventilator which may be adjusted to fitany width of window sash, and which shall be rain and snow proof, at the same time that ample ventilation shall be afforded without excessive or undue draft.

The invention consists of that certain novel construction to be hereinafter particularly pointed out and claimed in which the ventilator embodies a hollow tubular structure constructed in telescopic sections. adjustable for varying widths of window sash by pulling the sections apart or pushing them together, and in which ventilation is provided through a series of openings in one side in one section of the ventilator and through the opposite side of the other section,

In the drawings,

Figure 1 is a perspective view of the inside of a window sash with my ventilator applied thereto, one. side of the window frame being in cross section.

Fig. 2 is a perspective view of the ventilator taken from the outside.

Fig. 8 is a cross section of the same.

The ventilator is preferably constructed of sheet metal formed in rectangular tubes 1 and 2, one of th sections, as 2, bein mace slightly smaller than the other section for telescopic engagement therewith, handles 3 being provided for the ends of the sections for ready adjustment. The rectangular tubes are formed with the lap seams a, l, at

' the bottom so that any rain or moisture which might collect within the tubes can readily run out.

The upper edge for the inside of each section is formed with an upwardly extending flange 5, 6, the flange on the outer telescopic Specification of Letters Patent.

Serial No. 227,001.

section being formed of suflicient dimensions to receive the flange of the other section, and to serve as a proper guide and brace for the sections they are adjusted a corresponding head 7, 8, is provided in the side wall of each section immediately below the flanges 5, 6.

A series of openings 9, 10, preferably circular, are provided in the opposite side walls of the two sections, one set for the outside of ,the window opening and the other for the inside. The flanges 5, 6, of the sections are cut away at the ends at 12. 13,

and the ventilator is inserted in the window frame 14, resting on the sill 15, the lower sash being raised, with the sections drawn out so that the ends will fit between the sash stops with the flanges 5, 6, on the insid of the window opening.

The lower sash 16 is then. lowered to rest upon the ventilator with the flange engaging the inner face of the lower sash rail, thus effectively sealing the opening which would be left if the flanges were not provided, by reason of the fact that one of the sections is somewhat smaller than the other.

In the use of the ventilator, the air enters the openings on the outside and passes through the hollow tube to the openings on the inside at the opposite side, so that all direct draft is eliminated. No rain can drive in either through the ventilator or between the ventilator and the sash.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

As a new article of manufacture. the ventilator adapted to be inserted in the window frame underneath the lower sash, comprising two telescopic tubular sections provided with openings in the outer wall at one end of one section and in the inner wall at the opposite end of the other section, each section provided with an upwardly extending flange to fit over the sash and a bead underneath the flange to serve as a guide for the telescopic sections, with the bead and flange cut away at their outer ends to permit the insertion of the ends of the ventilator between the sash stops.
